The purpose of the research is formation of
passenger transport policy by public transport from the
standpoint of determining the level of safety in COVID-19 and
passenger comfort with the development of basics for
measuring the perception of the most important factors of
public transport convenience, minimum discomfort and
maximum safety.
Methodology. The study was conducted in two stages - inhouse and experimental – the collection and processing of data
obtained from the survey of passenger flows. Continuous field
research by the tabular method which in comparison with the
existing ones is the most time-consuming, but the only one that
can provide maximum accuracy of passenger information for
further processing of the obtained statistical data of the studied
system of public transport. The information obtained by
organoleptic means was entered for further processing in the
special accounting map, then calculations were performed for
traffic areas between the stopping points of each studied route.
Findings. The results of field research using the model of
discomfort allow us to correctly predict the choice of mode of
transport and the behaviour of passengers when using public
transport in medium-sized cities. It is proved that the artificial
underloading of the vehicle to avoid tight contact of
passengers does not affect the level of infection with the virus
of COVID-19 and, therefore, this restriction is not appropriate.
Conclusions. Formation of the strategy of passengers'
transportation in the conditions of COVID-19 is possible only
with the use of the characteristic indicators of the
transportation of people established by the multi-criteria
analysis of a transport network – the level of discomfort,
vehicle filling factor, the average time of transportation, the
average distance of transportation. It is obligatory to use such
means of protection as masks and gloves, provide the
enhanced ventilation of the salon, and organize passengers'
boarding through the back door with 100 % contactless fare
payment.

Aerated concrete with the use of ferruginous quartzite processing waste
(Видавництво Львівської політехніки, 2020-10-10) Malovanyy, Myroslav; Ilyash, Oksana; Povzun, Oleksiy; Kalynychenko, Valeriy; Bylym, Ludmyla; Kasich, Vitaliy; Lviv Polytechnic National University; Yuri Kondratyuk National Polytechnic University of Poltava; Donetsk National Technical University
Waste (tailings) of mining and processing plants of
Kryvbas were studied by the stages of their magnetic
enrichment. The granulometric compositions of the tailings,
the amount of iron (total and magnetic) and the mass fraction
of solid in them are determined. The expediency of disposing
of ferruginous quartzite waste at the first stage of enrichment
as a silica component in cellular concretes is proved. Optimal
compositions of aerated concrete mixtures are determined
based on the following criteria: the average density of cellular
concrete in the dry state and its compressive strength.

Development of detergent recipe with improved environmental characteristics
(Видавництво Львівської політехніки, 2020-10-10) Slyva, Yuliia; Verenikin, Oleksiy; National University of Life and Environmental Sciences of Ukraine
The research on the development of an innovative
formula of a synthetic detergent with improved environmental
properties, which meet the environmental standard of SOU OEM 08.002.12.065:2016 “Detergents and cleaning products.
Environmental criteria for life cycle assessment” is carried out.
The accumulated theoretical and practical experience is
generalized, the general scheme of designing and development
of new goods taking into account features of detergents with
the improved ecological characteristics is created.

The assessment of the environmental performance management in Ukrainian airports
(Видавництво Львівської політехніки, 2020-10-10) Radomska, Margaryta; Mushta, Marina; National Aviation University
The comparative analysis of the environmental
policy and performance of Ukrainian airports was conducted
using specially defined parameters. To improve the existing
situation we have developed recommendations on the list and
content of environmental documents to be developed and
implemented at Ukrainian airports, as well as possible regional
environmental aspects of airports to be accounted in their policy.

Clean utilization of municipal solid wastes and alternative fuels derived from it
(Видавництво Львівської політехніки, 2020-10-10) Topal, Alexander; Holenko, Iryna; Haponych, Luidmyla; Coal Energy Technology Institute of National Academy of Sciences of Ukraine
For the municipal solid waste (MSW) to be used in
a proper way, it is necessary to implement clean technologies
capable of thermal treatment of MSW and RDF in order to
produce heat and electricity while meeting current ecological
requirements. Nowadays, a number of technologies for
MSW/RDF thermal treating are being used worldwide. Among
them, the most proven technologies, applicable for industrial
introduction, have been considered while analyzing their
advantages/ disadvantages accounting for local conditions of
Ukraine.
